PHP变量和MySQL查询

Question

Wasn't sure what exactly to search for so apologies if this has been covered elsewhere..

Basically I have Bulkhead1, Bulkhead2, Bulkhead3 etc and I'm trying to save space by adding 1 each time but I'm going wrong somewhere! :(

Something is going wrong here - $row['Bulkhead"'.$it.'"']

$i=1;
while($x= mysqli_fetch_array($y)) { 
$bh = $row['Bulkhead"'.$it.'"'];
}
$i++;

Answer 1

try; $bh = $row['Bulkhead'.$i];

Answer 2

I think that the double quotes are misused, also you are using $i and $it, is it a typo?

$i=1;
while($x= mysqli_fetch_array($y)) { 
    $bh = $row["Bulkhead$i"];
    $i++;
}

Answer 3

I don't really understand what you want but I will try to fix your code:

    $i=1;
    while($x= mysqli_fetch_array($y))
    { 
   echo 'Bulkhead'. $i;
   $i++;
    }

Or as an array:

$bh  = array ();
$i=1;
while($x= mysqli_fetch_array($y))
{ 
   $ bh[ ]= 'Bulkhead'. $i;
   $i++;
}

If I get you wrong, try to explain your question better.
